How many Canadian women armed forces died in world war 2?

None were killed by enemy action. Of the 156 Canadian Womens' Army
Corp members who served in northwest Europe (an additional 46
served in Italy), four were wounded by a V-2 strike on Antwerp in
1945. (There were also CWACs in England, and in Washington DC).
There were perhaps some deaths due to accident or illness. In the
post war months more CWACs served in Europe, eventually around
3,000, helping repatriate the Canadian Army. There were no
casulaties among the Women's Division of the Royal Canadian Air
Force, or the Women's Royal Canadian Naval Service.
